A CORPORATION 0F LLLNS' '.BARBERS CHAIR Application filed July 8,

is to provide'novel means for guiding the' head rest slide and holdingit in its various positions of adjustment. Another object is to providenovel means for fastening the slide guiding means tothe framework of thechair back. Another object is to provide simple and efficient means forsecuring together the woodeny framework of thechair back and themarginal metal frame member thereof.

With these and other objects and advantages in view, this inventionconsists inthe several novel features of construction, arrangement andcombinationsof parts hereinafter fully set forth'and claimed.

The invention is clearly illustrated in tht` 2o drawing accompanyingthis specification in which Figure 1 is a rear elevation of a fragmentof a chair back embodying a simple vform of the present invention;

Fig. 2 is a detail central vertical cross section taken on the line 2-2of Fig. 1';

Fig. 3 is a detail `vertical longitudinal section taken on theV line 3-3of Fig. 2;

Fig. l1 is -a detail horizontal section taken f v on the line 4`l ofFig. 3;

Fig. `5 is a side elevation of a -fragment of the marginal frame memberlooking in the direction of the arrow 5 in Fig. 2; and

Fig.' 6 is al perspective view of a collarv employed for securing theupper Vend of the marginal frame member kto the wooden framework of thechair back.

' Referring to said drawing; the reference characters, 6, 6?, 7 andP@designate horizontal 60 and vertical-frame members which comprise theframework: of the chair back. rhese members are preferably formed ofwood;

glued and .otherwise rigidly secured together.

. as b y dowel pins to form a strong and substantial framework.

A marginal framefmember 8, preferably formedV of enameled metal waresurrounds the framework of the back, and its lower end is securedthereto in any suitable manner, as,

5 for instance, by nscrewsiIL which enter the 1929. Serial No. 376,684.

wooden framework from below. A metallic sheet, or other suitable sheetof material', 9 is rigidly held between the .framework and marginalframe member 8. The marginal frame member 8 preferably comprises astruct5 ture, angle shaped in cross section, .having a flange 10 whichoverlies the back sheet 9 and a flange 11 which over-lies the edgeportion of the framework. i

A slide or slide bar 12 for the" head rest (not shown) is provided, asusu'al,and said slide enters a vertical groove 7*?. formed in themembers.7 6, @aand Z of the wooden framework through a slotor opening 13in they upper horizontal flange 11 of :the marginal frame member 8. Aguide member. lill is providedfor guiding the slide 12 in the chairback, andsaid' guide member is formed `with a vertical guideway orchannel 15 (see Figs. 8 and 4) in which the slide is slidably guided.Theguide member 14 is contained in the vertical groove 7b; as seen inFigs.A 8 and 4, and is rigidly secured to the 'framework screws 16 whichpass. through the wooden A framework and are threaded. inV plates orbars 17 which act as nuts andare secured to the` opposite side of thewooden'framework by screws 17a. rlhe bars or plates 17d have tappedholes 'for the reception of theV screws 16', and being rigidly fastenedto the wooden 8G framework., they will not drop into the upholstery whenthe screws 16 are unscrewed therefrom, as would be Athe case were ordiynary nuts employed on the ends of the screws. Should occasion requirethe removal of the guide member 1 4-, this may be conveniently donewithout any danger of the nuts becoming displaced. ln order to obtainaccess to the headslo'f the screws,the wallrlflfL of the r guide memberis formed with Vapertures 19 arranged in alignment with the a-Xes of thescrews 16, as is clearly illustrated. in Figs. and 4. y Y A rectangularcollar-:2O is employed for rigidly holding the upper end of the margi-95 nal frame member 8 in place on the wooden framework. Saidcollarhas arectangular opening QOtherethrough-for the passage of the slide 12 andit is formed withV downwardly projecting lianges 20bfwhich enter theopening 13 in the marginal frame member 8. It is also formed with amarginal top plate 2Oc that lies upon the upper face of the marginalframe member 8 and completely covers the opening 13 with the exceptionof the slot for the slide 12. The rectangular sleeve is provided withscrew holes for the reception of screws 21 which are threadedly engagedin laterally extending ears 18c formed at the upper end of the guidemember 14. Above the ears 18, the guide member 14 is formed with a neckportion 18d that enters a socket in the collar formed between the sideflanges 20b thereof.

In assembling the marginal frame member 8 with the wooden framework, theneck portion 18d of the guide member 14 is inserted into the opening 13of the marginal frame member and the lower end of the marginal framemember is then swung against the wooden framework and its lower endsecured in place with the screws 8a. Thereafter, the flanges 20b of thecollar 2O are inserted through the opening 13 in the marginal framemember, the neck portion 18d of the guide member 14 entering the socketin the collar 20, after which the screws 21 are inserted and screweddown, thereby rigidly connecting the collar with the guide member. It isto be observed that a rigid connection is obtained between the woodenframework and the marginal frame member 8 which takes all of the strainoff the screws 21, inasmuch as the neck portion 18d of the guide member14 fits fairly tight in the socket of the collar 20, and the flanges ofthe collar fit fairly tight in the slot or opening 13 of the marginalframe member 8.

The slide 12 is formed with teeth 22 on one side, which teeth co-operatewith a latch in the form of a dog or pawl 23, whereby the slide may beheld in any vertical position of adjustment. The dog 23 is pivotallyconnected to the guide member 14 by a pin 24 which is secured in ears 25formed on the wall 18a of the guide member. The upper end of the dogpass-es through a slot in the wall 18a of the guide member and isyieldingly held in engagement with a tooth of the slide by a spring 26interposed between the wall 18 and an armV 27'v of the dog. Y

Itwill be observed that by depressing said arm 27 of the dog, the latterwill be disengaged from the slide 12 whereupon the same may be loweredto any position of adjustment, and when the dog is released, it willengage with the adjacent tooth and support the slide in such adjustedposition. The teeth of the slide are preferably in the form of ratchetteeth, as shown, whereby the slide may be withdrawn by merely pullingthe same out of the chair back.

A push button 28l is provided for actuating the pawl or dog 23., andsai'dpush button is held in an apertureV contained in a depending lug 29which is formed upon the marginal frame member 8. The push button islocated behind the arm 27 of the dog 23 in position to engage the samewhen pressed inwardly, and a spiral spring 3() is provided Vforreturning the push button to its normal position. As

shown, the push button is slightly tapered i 29 from the rear thereof,after which they spiral spring may be inserted into the socket 31through the upper open end thereof, the smaller convolution of thespring being placed over the smaller end of the push button. From thisit will be observed that the spring actuated push button is separatelymounted in the marginal frame kmember 8,

whereas the dog or pawl is mounted on the guide member 14. Thisarrangement enables the guidemember, together with the dog or pawl, tobe assembled with theframework of the chair back, after which the sheetbacking 9 and marginal 'frame member 8 with the push button 28 containedtherein may be secured to the framework in assembling the parts. Theframework may be upholstered in the usual manner, a fragment of which isseen at 32.
